Guerbet, a global leader in medical imaging with more than 30 years of experience in MRI, and the first to bring a macrocyclic GBCA to the global market, is proud to announce the U.S. Food and Drug Administration (FDA) has approved Elucirem™ (gadopiclenol) injection. This next generation, highly stable macrocyclic gadolinium-based contrast agent (GBCA), has the highest relaxivity in its class for magnetic resonance imaging (MRI) and is indicated for use in adults and children aged 2 years and older.4 FDA granted Elucirem™ priority review, a designation assigned to applications for drugs that provide significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions compared to available therapies.5

GBCAs improve the contrast between lesions and surrounding tissues by accelerating the relaxation of protons thanks to interaction with gadolinium atoms. Gadopiclenol, the active substance of Elucirem™, has been designed to enable twice as much interaction, resulting in the highest relaxivity among all non-specific GBCAs.4 This allows use at half the conventional dose of other non-specific GBCAs.

Elucirem™ (Gadopiclenol) Injection is used to detect and visualize lesions with abnormal vascularity in the central nervous system (brain, spine and associated tissues), and the body (head and neck, thorax, abdomen, pelvis and musculoskeletal system).

Guerbet is a leader in the field of GBCA-based MRI imaging agents and developed the first macrocyclic GBCA. We are extremely gratified that this approval from the FDA will make it possible for clinicians and patients to benefit from the innovations brought by Elucirem™” said David Hale, Chief Executive Officer of Guerbet.

The approval was primarily based on data from two adequate and well-controlled Phase III studies completed in March 2021 which showed that gadopiclenol was designed to improve image quality in brain and body MRI at half the conventional gadolinium dose.2,3  In both the PICTURE trial for CNS MRI and the PROMISE trial in Body MRI, gadopiclenol-enhanced MRI at 0.05 mmol/kg showed superiority as compared to unenhanced MRI and non-inferiority as compared to gadobutrol at 0.1 mmol/kg as assessed in 3 lesion visualization co-primary criteria: border delineation, internal morphology and contrast enhancement.2,3  In the PICTURE trial, readers preferred the quality of visualization obtained with a half dose of Gadopiclenol compared to a full dose of Gadobutrol.2

Gadopiclenol was evaluated in 1,047 patients with doses ranging from 0.025 mmol/kg BW (one half the recommended dose) to 0.3 mmol/kg BW (six times the recommended dose). A total of 708 patients (age range two years to 88 years) received the recommended dose of 0.05 mmol/kg BW. No major safety signals were reported during the development of gadopiclenol, and the adverse reactions reported during the two-Phase III studies were similar for both products administered.  The most common adverse reactions (incidence >0.2%) in patients who received Gadopiclenol were injection site pain, headache, nausea, injection site warmth and coldness, dizziness, and localized swelling.

“After 15 years of dedicated research to bring Elucirem to fruition Guerbet is very proud of this FDA approval of Elucirem™, confirming the commitment of Guerbet’s R&D teams in developing solutions for MRI, adapted to the needs of radiologists and patients.” said Dr Philippe Bourrinet, Senior Vice-President Development, Medical & Regulatory Affairs of Guerbet.

Elucirem™ will be available in glass vials, pharmacy bulk package and plastic pre-filled syringes which can help to streamline workflow in the imaging suite.  It will be manufactured by Liebel-Flarsheim™ Company LLC, a Guerbet Group company, in Raleigh, North Carolina.
